Effect of Picrasma quassioides plant extract, yeast culture and monensin on in vitro mixed ruminal microorganism fermentation of wheat starch
The objective of this study was to compare the plant extract from Picrasma quassioides (EPQ), yeast culture and monensin on in vitro rumen fermentation characteristics of wheat starch. Compared with the control (no additive), EPQ decreased the dry matter digestibility and the total VFA production (P＜0.05), and increased the ratio of acetate and propionate. Both EPQ and yeast culture increased the final rumen pH (P＜0.05), but monensin had a negative effect on decline of rumen pH. In conclusion, the addition of EPQ can efficiently retard rumen fermentation rate of wheat starch in vitro, and increase the final pH of ruminal fluid.
